Write the equilibrium-constant expression for the reactionA(s)+3B(l)↽−−⇀2C(aq)+D(aq)A(s)+3B(l)↽−−⇀2C(aq)+D(aq)in terms of [A], [

Ilia_Sergeevich [38]

Answer:

$K_{c} = [\text{C}]^{2}[\text{[D]}$

Explanation:

$\rm A(s)+3B(l) \, \rightleftharpoons \, 2C(aq)+D(aq)$

The general formula for an equilibrium constant expression is

$K_{c} = \dfrac{[\text{Products}]}{[\text{Reactants}]}$

Solids and liquids are not included in the equilibrium constant expression.

Thus, for this reaction,

$K_{c} = [\textbf{C}]^{\mathbf{2}}\textbf{[D]}$

Which of the following types of equations will include spectator ions

krek1111 [17]

Answer:- B) Full ionic equation

Explanations:- A molecular equation does not have ions. It is the non charge form of the elements of compounds. When we write the full or total ionic equation for the molecular equation then ions are written for the aqueous species. The ions present on both sides(reactant and product sides) in a full ionic equation are known as spectator ions or common ions. These ions are canceled to get the net ionic equation. For example, reaction of aqueous solution of silver nitrate with aqueous solution of barium chloride to form aqueous solution of barium nitrate and a precipitate of silver chloride.

Balanced molecular equation:-

$BaCl_2(aq)+2AgNO_3(aq)\rightarrow Ba(NO_3)_2(aq)+2AgCl(s)$

Full ionic equation:-

$Ba^+^2(aq)+2Cl^-(aq)+2Ag^+(aq)+2NO_3^-(aq)\rightarrow Ba^+^2(aq)+2NO_3^-(aq)+2AgCl(s)$

If we look at the above full ionic equation then barium ion and nitrate ions are the spectator ions are they are present on both sides.

So, while writing the net ionic equation, these spectator ions are canceled.

Net ionic equation:-

$2Cl^-(aq)+2Ag^+(aq)\rightarrow2AgCl(s)$

So, it is also clear from the above example that it's the full ionic equation that include spectator ions.

what is the concentration (molarity) of a solution that has 0.150 moles of sodium chloride dissolved in 0.900 L solution

Alexxx [7]

Answer:

Molarity= 0.167M

Explanation:

n= 0.15mol, V= 0.9, C= ?

Applying n= CV

0.15= C× 0.9

C= 0.167M

Write and balance the equation for the dissolving of aluminium chloride into an aqueous solution with the dissociation of

umka2103 [35]

The balanced equation for the dissolving of aluminum chloride into an aqueous solution with the dissociation of the ions is; AlCl3(s) → Al^3+ (aq) + 3 Cl^-(aq).

<h3>What is an equation?</h3>

An equation is a representation of the change that occurs inside a reaction vessel. Usually, we use this tool to show on paper, a process that we can not see with or eyes.

The equation that shows the balanced equation for the dissolving of aluminum chloride into an aqueous solution with the dissociation of the ions is; AlCl3(s) → Al^3+ (aq) + 3 Cl^-(aq).
